Question

【題目】Read the passage and choose the best answer（根據短文內容，選擇最恰當的答案）：

Dinosaurs were the dominant land animals for 160 million years, making them one of the most successful groups of animals ever. However, all the dinosaurs that were living 65 million years ago went extinct. About 70% of all animal life on the earth died out. Scientists call it a mass extinction（大滅絕）.

Having existed for 165 million years, why did dinosaurs die out? There are many different theories about why this happened. We will probably never know exactly what happened, which means that scientists will continue to disagree and come up with different dinosaur extinction theories. Here are two of them:

Ice Age Theory

Now and again, the earth cools into periods we call ice ages. As dinosaurs were thought to be cold blooded, it was hard for them to cope with such cold conditions.

Disease

It is possible that a disease spread through the dinosaur population causing their extinction.

Scientists have come up with some strange ideas but none of the theories really explains everything, so we will probably never be sure what happened.

【1】The underlined word “dominant” in the passage probably means _________.

A.biggestB.powerfulC.strangeD.special

【2】Why did the dinosaurs become extinct? ___________.

A.Dinosaurs could not suffer from cold weatherB.A disease spread through the dinosaur population

C.Other species became stronger than dinosaursD.We have not known about the truth yet

【3】Dinosaurs existed on the earth for _______ million years.

A.160B.165C.65D.115

Answer 1

【答案】

【1】B

【2】D

【3】B

【解析】

文章主要介紹了科學家們就“恐龍滅絕”這個理論做了各種的推測，但是沒有一個理論是成立的，且在文中列舉出其中的兩個理論。

【1】詞義猜測題。根據文中making them one of the most successful groups of animals ever.“使它們成為有史以來最成功的動物群之一”，可知，dominant指的是“占統(tǒng)治地位的，主導的”，故選B。

【2】細節(jié)理解題。根據文中Having existed for 165 million years, why did dinosaurs die out? There are many different theories about why this happened. We will probably never know exactly what happened, which means that scientists will continue to disagree and come up with different dinosaur extinction theories.恐龍已經存在1億6500萬年了，為什么恐龍滅絕了？關于為什么會發(fā)生這種情況，有很多不同的理論。我們可能永遠也不知道到底發(fā)生了什么，這意味著科學家們將繼續(xù)持不同意見，提出不同的恐龍滅絕理論。和文中Scientists have come up with some strange ideas but none of the theories really explains everything, so we will probably never be sure what happened.科學家們提出了一些奇怪的想法，但沒有一種理論能真正解釋這一切，所以我們可能永遠無法確定到底發(fā)生了什么�？芍�，沒有人知道恐龍為什么會滅絕，故選D。

【3】細節(jié)理解題。根據文中Having existed for 165 million years, why did dinosaurs die out?恐龍已經存在1億6500萬年了，為什么恐龍滅絕了？可知，已經生活了1億6500萬年，故選B。

細節(jié)理解類的閱讀理解是屬于直接解答性問題，是閱讀理解題中最簡單的一種，多數屬中低難度的送分題。但由于中考所占的比例很大，應特別引起注意。比如第三小題Dinosaurs existed on the earth for _______ million years. A. 160 B. 165 C. 65 D. 115根據文中Having existed for 165 million years, why did dinosaurs die out?恐龍已經存在1億6500萬年了，為什么恐龍滅絕了？即可知道答案。
